As herein illustratedhhoth-legs'of the staple are deflected away from eachother, or'spread apart, as.:.they are being driven, and curved v laterally of the cross-bar, Convenient means "for accomplishing the object in view com- "prises adeflecting member or baflle plate for curving the legs during the I staple-driving 1 operation ;in the manner disclosed in the r'fAsrnnine-msnnrine MACHINE, a

the legs in the desired directions lengthwise ofthe cross-bar while they are being driven and curved. The Staple is thus; anchored in the Work by the combined effect 10f.,the curvature of the legs laterally of the crossbar and their deflection lengthwise of the cross-bar. y 1' v v i The r invention further provides novel means" for varying the curvaturewhereby fasten'ings are ,anchored'in work. It is sometimes desirable, in operating fiupon shoes to fasten the upper to the insole, to curve the legs of upper-fastening" staples differently in operatinglupon diiferent portions of the same shoe, for examples in the manufacture of a type of shoe in which the counter," at one side at least, extends forwardly into the shank portion of the shoe. 7 Where thereis thus an extra" thickness of the' upper materials the legs of the staple should be curved on a 'longer radiusin order that they may secure an efi'ectivehold in the substance of the insole; A 's herein illustrated, a single deflecting rmember is provided tori curving both-legsjand associated with this member is mechanism for efi'ectin'ge substantially instantaneous adjustmentthereofto varythe' curvature of'the legs.
